Not able to complete an order (Error 500) [SOLVED]

[mucchina74]

Hello!

I'm building a new prestashop site. I have the Cash On Delivery as only possible payment method.
When the user clicks on "Order with need of payment" I get and HTTP Error 500, even if the order is correctly visible in the admin site, and the same error occurs when I try to resend the email from the admin site.
The site URL involved is /module/ps_cashondelivery/validation
For the URL at admin level giving the same error, please look at the attached screenhot.

The email sending apparently is not the issue because the test email works fine.

Did some of you experience the same issue or can some of you help me on this?

The prestashop version is the 1.7.6.5.

Enabling the debug mode, here is the error:

(1/1) UndefinedFunctionException

Attempted to call function "idn_to_ascii" from the global namespace.

This function is part of the INTL PHP extension - you have to activate it through your webhoster panel or php.ini or contact your hoster to do so.
